This study focuses on the numerical simulations of the cone penetration tests in a sand ground. The mechanical responses of sand were described using the modified Mohr Coulomb plasticity model based on the critical state soil mechanics. In the plasticity model, the dilatancy angle was not a constant...

콘관입시험이란? | , 2003), 액상화 잠재성 판단(Stark and Olson, 1995)등에 활용되고 있다. 콘관입시험은 깊은 관입의 일종으로 강성이 큰 관입체가 강성이 작은 지반을 관입하는 과정이다. 깊은 관입의 수치해석을 수행할 때에는 지반 내 발생하는 대규모 변위 및 관입체와 지반사이에 마찰 저항을 반드시 고려해야 한다. | |
깊은 관입의 수치해석을 할 때 고려해야 하는 것은? | 콘관입시험은 깊은 관입의 일종으로 강성이 큰 관입체가 강성이 작은 지반을 관입하는 과정이다. 깊은 관입의 수치해석을 수행할 때에는 지반 내 발생하는 대규모 변위 및 관입체와 지반사이에 마찰 저항을 반드시 고려해야 한다. | |
지반의 대변형을 모사하기 위한 방법들의 한계는? | , 2013) 방법 등이 제안되어 왔다. 하지만 이러한 방법들은 복잡한 정식화 과정이 필요하며, 유한요소 해석 시 상당한 추가 연산을 요구하고, 또한, 격자의 재설정시 응력, 변형률, 간극비와 같은 상태 변수들의 내삽(혹은 외삽)을 요구한다. Hügel et al. |
